How long does a RI take to clear up?!

[SatanicIntention]

Take your snake to the vet, get a culture done so you KNOW what antibiotic will work, and pay the bill. You took on the responsibility of this animal, and sick or not, you need to provide the absolute best care you can. If that means finding him another home who can do so, then by all means, do it.

Antibiotics that come to mind that start with A are Amikacin and Amoxicillin. Amox will NOT work. If the antibiotic is Amikacin, and he's already had 3 shots and isn't at least looking a bit better, then it's not going to work. Getting another injection of it won't do anything other than prolong the infection and make it more resistant.

This snake is your responsibility and regardless of how much you paid, it is your priority to take the best care of him as you possibly can. You wouldn't adopt a dog from the animal shelter and just chain it up in the backyard suffering from ticks, fleas, heartworms, without a shelter, proper food and water and not vaccinating the dog, would you?

My friend adopted a rat from the pet store 2-3 years ago and when the rat came down with pneumonia, she took it to the emergency clinic. $1200 later, she had a dead rat. Pnut likely cost her $10 max.

When you take on the responsibility of an animal, their care is up to you. If you cannot provide proper care, then find someone who can.

Also, how are you housing the snake? What are his temperatures/humidity? While he is sick, bump the temperatures up to 95-96 warm side and 85-86 cool side with 70% humidity(not wet, humid). This will help him feel more comfortable until you can get him to an actual veterinarian who will treat him. You cannot put off vet treatment any longer or the snake will die from drowning in its own fluids.
